I’d say don’t be hesitant to try to get her into things. Don’t push it multiple times, but if she’s genuinely never heard of, for example, South Park, just show her an episode. If she doesn’t like it, that’s that and it’s not your fault or anything and it sounds like she’s at least willing to give things a shot for you.

Then of course try to find things you’ll both like. But do it together cause it’s more fun that way and it sucks to feel like you’re the only one trying.

But also maybe you don’t have a ton of interests to share and just enjoy each other’s company and that’s fine 🤷

Serious question, is there actually a FOSS project out there at the scale of something like Firefox that survives on only donations?
